Details
PHP 8.1 requires classes which implement Iterator to have all Iterator methods declared with appropriate return types or annotated with #[\ReturnTypeWillChange]. In my (limited) understanding we cannot declare return types while remaining backward-compatible, thus annotate. Closes T15835 Run PHPStan static code analyzer, see no warnings anymore.
